X-rays

For thousands of years, physicians were limited to observing external symptoms and listening to a patient's own descriptions in order to diagnose disease. All that changed in 1895 when an accidental discovery led to one of the most indispensable tools in medicine. Wilhelm Conrad Roentgen's discovery of x-rays allowed doctors for the first time to observe the inner workings of the human body. Immediately recognized as an important diagnostic tool, the x-ray ultimately led to such modern medical advances as computerized axial tomography (CAT scans), magnetic resonance imaging (MRI), and radiation therapy as a weapon in the fight against disease.Blohm, Craig E. is the author of 'X-rays ' with ISBN 9781560069331 and ISBN 1560069333.
